This paper presents results of research of reinforced concrete elements subjected to combined axial load and bending with different percentage of additional reinforcement. As an additional reinforcement there was used carbon laminate with width of 25 and 50 mm. The comparative analysis was carried out and strengthened effectiveness was determined.

PL

W artykule przedstawiono wyniki badań wzmocnionych elementów żelbetowych narażonych na jednoczesne działanie obciążenia osiowego oraz zginania z zastosowanym różnym procentem dodatkowego zbrojenia. Jako dodatkowego zbrojenia użyto laminatu węglowego o szerokościach 25 i 50 mm. Przeprowadzono analizę porównawczą i określono skuteczność wzmocnienia.
